I've owned the Regency Alterra Ci1150 for about 2 years now. I feel this is a terrible wood stove for many reasons and I regret the decision of ever replacing our old Osborn stove with it. We hardly use it now since I feel it's not worth the environmental trade off of burning wood and not benefiting from any real warmth from it as it does not heat our room to a comfortable level. There are also a number of other issues I have with this stove, not to mention a few safety concerns. The only time I have ever really felt any kind of heat from this stove is when I open the door. One positive, I will say that It is a beautiful wood stove, that is one of the reasons we bought it, unfortunately.
